42CA hexadecimal to binary

Here we will show you how to convert the hexadecimal number 42CA to a binary number. First note that the hexadecimal number system has sixteen different digits (0 1 2 3 4 5 6 7 8 9 A B C D E F) and the binary number system has only two different digits (0 and 1).

The four steps used to convert 42CA from hexadecimal to binary are explained below.

Step 1)
Multiply the last digit in 42CA by 16⁰, multiply the second to last digit in 42CA by 16¹, multiply the third to last digit in 42CA by 16², multiply the fourth to last digit in 42CA by 16³, and so on, until all the digits are used.

A × 16⁰ = 10
C × 16¹ = 192
2 × 16² = 512
4 × 16³ = 16384

Remember that the hexadecimal number system has sixteen different digits, so when doing the above calculation, we use the following values if applicable: A=10, B=11, C=12, D=13, E=14, and F=15.

Step 2)
Next, we add up all the products we got from Step 1, like this:

10 + 192 + 512 + 16384 = 17098

Step 3)
Now we divide the sum from Step 2 by 2. Put the remainder aside. Then divide the whole part by 2 again, and put the remainder aside again. Keep doing this until the whole part is 0.

17098 ÷ 2 = 8549 with 0 remainder
8549 ÷ 2 = 4274 with 1 remainder
4274 ÷ 2 = 2137 with 0 remainder
2137 ÷ 2 = 1068 with 1 remainder
1068 ÷ 2 = 534 with 0 remainder
534 ÷ 2 = 267 with 0 remainder
267 ÷ 2 = 133 with 1 remainder
133 ÷ 2 = 66 with 1 remainder
66 ÷ 2 = 33 with 0 remainder
33 ÷ 2 = 16 with 1 remainder
16 ÷ 2 = 8 with 0 remainder
8 ÷ 2 = 4 with 0 remainder
4 ÷ 2 = 2 with 0 remainder
2 ÷ 2 = 1 with 0 remainder
1 ÷ 2 = 0 with 1 remainder

Step 4)
In the final step, we take the remainders from Step 3 and put them together in reverse order to get our answer to 42CA hexadecimal to binary:

42CA hexadecimal = 100001011001010 binary
